This report covers the CLP Group’s sustainability performance for the calendar year ending 31 December 2022. It is published at the same time as the CLP 2022 Annual Report. The CLP 2021 Sustainability and Annual Reports were published in March 2022.
CLP reviews its reporting scope regularly to ensure the material impact of the Group’s overall portfolio is covered. Any assets that have been operating and sold during the year are reflected in the reporting scope. In 2022, additions to the reporting scope include the Tallawarra B gas-fired power station in Australia, Gongdao solar farm and Xundian II wind farm with battery storage in China. Shiheng Power Station has ceased to be owned by CLP since January. In November 2022, CLP sold its 70% interest in the coal-fired Fanchanggang Power Station in Mainland China. Divestment of 10% equity interest in Apraava Energy to CDPQ were completed in December 2022.
In 2022, the following data points have been adjusted:
Health, Safety and Environment (HSE): Due to organisational change, CLP has adjusted the disclosures of safety metrics. Data from CLP Holdings and Hong Kong are regrouped and reported under Hong Kong. Two existing environmental metrics, in the categories of total freshwater consumption and freshwater intensity of CLP’s power generation process, have been revised and are now independently assured.
Climate-related financial information: CLP has started to report the capital investments, operating earnings and revenues of each type of renewable energy individually, namely solar, hydro, wind and waste-to-energy. This change aligns with international reporting guidelines.
Our people: Total staff turnover rate is reported in employee metrics to align with international reporting practices.
Customers: Total electricity sold by sectors is newly reported. This provides transparency on the amount of usage of electricity in different sectors.
